APPARATUS FOR GENERATING ILLUltlllNATlNGr'C-|AS SPECIFICATION forming part of Letters Patent No. 779,842, dated January 10, 1905.

Application filed August 15, 1904. Serial No. 220,778.

Be it. known that l, FRANK .losur Fi vEAUx,

a citizen ot' the United States, residing at Alan1eda,in the county of Alameda and State of California, have invented certain new and l useful improvements in Apparatus for (ienl erating llluminating(las, of which the foll lowing is a specilieation. i

According'to this invention carbureted wa- I ter-gas is generated by introducing' oil and steam into a hot chamber, and water-gas is simultaneously generated by blasting' a bed of solid fuel to incamlescence and forcing' steam through it. ',lhe oil and water-gas are mixed and the mixture is passed through one or more superhcaters or iixers. 'lwo tixers heated to a high temperature by burning oil or other fuel therein, the products of combustion being then passed through the other tixer.

'lhe apparatus comprises a water-gas generator of the usual t vpe, a tower or other structure havingl an upper steam-superheater. an intermediate chamber with inlets for watergas, oil, and steam, and a lower initial fixer, and a combined supplemental heater and final tixer, the two tixers being connected at their lower ends. Y

The accompanying drawing is a longitudinal section of the apparatus on a vertical plane passing through the axes of `the-gene1ator, tower, and supplemental heater.

The water-gas generator A is of the usual type, comprisinga structure 1, having' a fuelgrate 2, an 'air-inlet 3 below the grate, steaminlets 4 4' below and above the grate, respectively, and lower and upper gas-outlets 5 5', controlled b,v valves 6 which open into the gas-main 7.

The tower B has at its middle portion a chamber t5, in the side of which is an opening 9 communicating with the .water-gas main 7. Pipes 1() serve for the introduction of oil and steam. Above the chamber 8 is a steamsuperheating chamber 1 1, which is nearly tilled with checker-work 12 and has upper inlets 13 for steam. At the upper end of this chamber is a waste-gas outlet 14, controlled by a cover 15. Below the chamber 8 is an initial fixer 16, containing checker-'work 17.

'lhe supplemental heater and tinaliixer C is a structure 18. the lower portion of which is tilled with checker-work 19. A pipe 2t), opening into the upper end of the preheater, serves for the intrinluction of liquid or gaseous fuel, usuali)v oil atomized by a .iet of .steam or air. A horizontal circumferential series of vports 21 serves for the introduction of air to burn the oil. The two iixers are connected at their lower ends by a passage 22, and the iixer C has an outlet 23 at its upper end, which delivers the tinished gas through a pipe .24 to the dip-pipe 25 of the sealed box Q6. A',

ln use oil or other fuell is tirst introduced into and burned in the, upper part of the charnber C, and the products of combustion pass down through the checker-work 19 and are delivered bv the passage 22 into the lower end of the initial tixer 16. The v then pass upward through the checker-work 17 of this fixer, through the chamber 8, through the checkerworh 12 o'f the steam-preheatcr 11, and iinallv escape through the outlet 14, the cover 15 being removed- During this period the fuel in the water-gas generator 1 is being blasted to incandescence, the hot products of combustion passing into chamber 8 through the checkerwork 12 and out at the top. and the superheater thus having been pre heated to therequisite temperature, steam is introduced alternately below and above the fuel in the generator A and the water-gas is passed into the chamber 8, where it is mixed with oil blown in through the pipes 10 by jets of steam. Steam is also introduced through the pipes 13 at the upper end of the towel'. passed downward through the checker-work A 12, which raises it to a high temperature, and

introduced into the chamber 8, where it assists in gasifving the oil. '.lhe mixture 0f watergas, gasitied oil, and steam is passed down through the hot checker-work 17 of the initial tixer and through the bottom passage 22 into the lower end of the final fixer, wherein it rises through the highly-heated checker-work 19, the tinished gas escaping through the ontlet 23. Y

The arrangement of the apparatus enables the final and initial xers to be heated to different regulated ternperatures, while the re- IOO the claims, refers to means supplemental` to the water-gas generator for heating the initial fixer.

I claim* 1. An apparatus for generating illuminating-gas, comprising a Water-gas generator., a carbureter, a fixer, and a supplemen tal heater, said generator and supplemental heater opening into opposite ends ofsaid fixer, as set forth.

2. An apparatus for generating illuminating-gas, comprising a water-gas generator, a carbureter, two connected fixers, and a supplemental heater for passing hot products of combustion through said fixers in a direction opposite to that in which the carbureted gas' travels, as set forth. 3. An apparatus for generating illuminating-gas, comprising a water-gas generator, a carbureter, an initial fixer, a supplemental heater and final fixer, said initial fixer connected at one end to said generator and at the other end to said final fixer, a source of heat in said final fixer, and an outlet for waste products from said initial fixer, as set forth.

4f. An apparatus for generating illuminating-gas, comprising a water-gas generator, a carbureter having inlets for oil and watergas and an outlet for waste products, and a fixer having at one end an inlet for hot products of combustion and communicating at the other end with said carbureter, as set forth.

5. An apparatus for generating illuminating-gas, comprising a water-gas generator, a oarbureting-chamber having inlets for oil and water-gas and an outlet for 4waste products, an initial fixer, and a supplemental heater and final fixer, said initial fixer communicating at one end with said carbureting-chamber and at the other end with said final fixer, as set forth.

6. An apparatus for generating illuminating-gas, comprising a water-gas generator, a carburetor, an intial fixer, anda supplemental heater and final fixer, said carbureter'having a water-gas inlet and opening into the upper end of said initial fixer, said initial and final fixers connected at their, lower ends, and said final fixer having vat its upper end ay fuel-inlet and a finished-gas outlet, as set forth.

7. An apparatus for generating illuminating-gas, comprising a water-gas generator, a steamsuperheater, a carbureting chamber with inlets for oil, water-gas and s u perheated ,and a tower vhaving an ,upper stearn-superA heater, an intermediate carbureting-chamber with inlets for oil, Water-gas and sup'erheated steam, and a lower fixer, as set forth. y
